Patented Dec. 14, A1931 UNITED STATES PATENT oF'FIcE 2.10am @TtltlmAppllctlon June 5, 1935, Seth! No. 25,033 s calma (crm-ss) My inventionrelates to a new and useful improvement in a combination truck andconveyer although from the description of the invention it will appearobvious that there are certain features of the invention which may beused independently of the combination with a truck or similar vehicle.It is an object of the present invention to provide a means forconveying material which is poured or dumped from a. truck to a distantpoint, within certain limits. As now commonly practised in dumping sand,gravel, coal and other loose material, and especially coal, it is oftennecessary to dump the contents of the lvehicle in a pile and then shovelthe pile of material into a container or through an opening. In theinvention I have provided a conveyer which will serve to receive thematerial as it is dumped from the truck and convey it to a distant pointor through an opening into a container,

even though this opening through whichthe material is to be passed iselevated.

It is another object of the invention to provide a device of this classwhich will be simple in structure, economical of manufacture, durableand highly efficient in use.

Another object of the invention is theprovision of a device which may beeasily and quickly attached in position for operation and removedtherefrom so that the driver of the vehicle will be required to spendbut little time in making the necessary adjustment for the invention.

Another object of the invention is the provision of a device of thiskind which will require a minimum alteration in trucks or similarvehicles of standard manufacture.

Another object of the invention is the provisicm of a conveyer of thisclass which may be used for conveying the material Y:from the rear ofthe vehicle and at various angles thereto.

Other objects will appear hereinafter.

'I'heai'vention consists in the combination land' arrangement of partshereinafter described and claimed.

The invention will be best understood by a v referenceto theaccompanying drawings which form. a part of this specification, and inwhich, Fig. 1 is a fragmentary, central, sectional view of a truckshowing the invention applied thereto and illustrated in side elevation.5o Fig. 2 is a longitudinal, vertical, sectional view of the conveyershowing it applied.

In the drawings I have illustrated the invention used with a vehiclehaving a chassis I4 on which is swingably mounted at the rear end a bodyIl. I'his body is shown in fragment in Fig. 15 1 in elevated position.It is moved t9) elevated position by means of thepiston rod llwhichprojects from the cylinder I'Ivwhich is supplied with air from the pumpIl operated by the shaft In this 20 gear boxl Il is slidably mounted onthe splined portion 2i of the shaft 22 a gear 23 which may be slid bymeans of the yoke 2l into mesh and out of mesh with the gear 2l which isflxedly mounted on the power take-of! shaft II. This 25 yoke 2l isiixedly mounted on the shaft 21 which isv pivotally connected to thelever 2l, intermediste its ends. One end of the lever Il is pivotallyconnected by means `of the pin Il to the lug Il which extends outwardlyfrom the hous- 30 ing 2l. The other end of the lever Il is connected tothe operating rod 3| which extends to a position accessible to thedriver of the vehicle. The power take-of! and the means of rotating theshaft I! together with the control therefor, 35 l is of standardconstruction and forms no part of the present invention.

Connected by the universal Joint l2 to the shaft 26 is a rearwardlyextended shaft 33 which extends through and is .iournaled in the bearingu. 40 Projecting outwardly from opposite sides` ofQthe shaft 33 beyondthe bearing 34 are trunnions or studs 35 and Il. A connecting shaft I1is provided having a universal fitting -3l at one end and provided atdiametricslly Opposite points 4,5

v with the bayonet slots l! which are adapted toandwhiclifcrmapai-tofthesupportingso` I frame. The shaft 43 is fixed tothe collars 4l and 45 which form a part of the bearings 44 and 45,respectively. This is preferably effected by a press fit. .'I'hebearings are supported in the housings 50 and," which are securedy tothe side walls 40 and 41 so that a spreading of these side walls isprevented as they bearings cannot move longitudinally of .the shaft 43.Each of the side walls 45 and 41 carries supporting Flxedly mounted onthe shaft 4l is axroller 54 which is cut away at 55 at its opposite endsto accommodate the bearings. The shaft 43 extends through the side walls4 and 41 at one end and in each of these side walls at the opposite endis formed an elongated slot 56 through which extends a shaft 51 on whichis rotatably mounted the roller 54. The shaft 51 as shown in Fig, 8projects beyond the outer face of the side walls 45 and 41 andAisprovided with a head 59 which serves as a swivel for one end of thescrew 50. This screw projects through a `nut 6I which is fixedly mountedon the side wall so that by rotating the screw GII the'roller 54 may bemoved toward and away from the rol1er'54 so as to retain in tautcondition the endless belt 52 which passes around these rollers andtravels between the side walls 46 and 41. v

Secured to the innerface of each `of the side walls at the upper andlower edges thereof, is an angle iron 63 which extends the length of thewall and serves as a guide for the conveyer belt 62. These angleironsare connected at the rear end of the conveyer by a transverselyextended plate 64 and located above this plate is the triangular-shapedreinforcing brace Il. A plate 60 similar to plate 64 connects the lowerset of angle irons at the forward end of the conveyer and serves as arest for the conveyer belt. 'I'hese plates 64, in addition to connectingthe opposite walls in xed relation and reinforcing the structure, alsoserve as a support for the belt to prevent its sagging. The angle irons0I also prevent the sagging of the belt when traveling.

As shown in Fig. 1 whenthe device is connected as illustrated ln Fig. 2the conveyer may be extended laterally at right angles to the vehicle ortruck or it may be extended at an inclination to the longitudinal axisof the truck on account of the swinging which is permitted through theuniversal connections indicated. It isl obvious that the free end of theconveyer may be elevated to any desired height withinits own limits sothat it may be projected through an opening I1 of a building or othersimilar'structure'into which it is desired to convey the material fromthe truck.

In Fig. 9 I have shown an attachment which permits the use of theconveyr when extended outwardly parallel to the length of the truck.This attachment comprises a housing Il projec'ting outwardly from whichis s. shaft Il having outwardly extending trunnions 1li for engaging inthe bayonet slot 4i of the universal fitting 40. Flxedly mounted on theshaft 55v within the hous- 4ing 60 is a bevel gear 1| adapted to meshwith the bevel gear 12 having the neck 13 engagingy in the sleeve 14.This neck is provided with the dlametrical slot 15 in which may engagethe ti'unn nions 42 carried on the end of the shaft 43. An

angle iron 15 is mounted on the housing 5 8 and adapted to abut againstthe side wall 41. l Side boards 18 and 11 are swingably mounted on theupper end of each of the side walls 46- and 41 to provide a guide forthe material which is being conveyed on the endless belt 62.' It isobvious that by shifting the gear 23 into one position or the other theshaft i8 may be caused to rotate so that control of the operation of thepump is provided.

It is believed obvious that the device may be very easily and quicklymounted in position for use andremoved therefrom. It is of such aconstruction that it is sufllciently light for a single operator toplace the conveyer on the truck when not in use so that it may beconveyed from place to'place with the load which is to be delivered.

While I have illustrated and described the preferred form of myinvention, I do not wish to limit myself to the precise details ofstructure shown but desire to avail myself of such modifications andvariations as may come within the scope of the appended claims.

Having thus described my invention, what I longitudinally thereof; atransversely'extending plate connecting said side plates at theiropposite ends, said transversely extending side plate being positionedbelow and spaced from the lower of said angle irons; a roller rotatablymounted between said side plates atv each end thereof, said rollersbeing located to position the periphery.
